phase composition

What Techniques are Used to Analyze Phase Composition?

Several analytical techniques are employed to study the phase composition in catalytic systems:

X-ray Diffraction (XRD): Used to identify crystalline phases and determine their proportions.
Scanning Electron Microscopy (SEM): Provides images of the catalyst surface, revealing the distribution of different phases.
Transmission Electron Microscopy (TEM): Offers high-resolution images to study the morphology and distribution of phases at the nanoscale.
Energy Dispersive X-ray Spectroscopy (EDS): Used in conjunction with SEM or TEM to analyze the elemental composition of different phases.
Thermogravimetric Analysis (TGA): Measures the change in weight as a function of temperature, providing information about phase transitions.
